DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for constructing a vast building.

[0002]

2. Description of the Related Art Conventionally, when constructing a relatively large building, the construction as shown in FIG. 3 is performed due to the limitation of the working range determined by the radius of rotation of a lifting crane which lifts and carries in building materials. Done. That is, a large building is divided into sections so that the lifting crane 10 can be used.
The construction in the range A is divided into the range A and the range B, and the construction is performed from the outer periphery of the building and the range B. Then, after the construction in the A range is completed and the structures 2 and 3 are completed, the construction in the B range is divided into a plurality of sections as shown in FIGS. Lifting crane 1
0, and thereafter, as the construction of the structure proceeds, the structure 1 in the B range is constructed by moving the lifting crane 10 to the other end of the B range. In this way, the structures in the range A and the structures 1, 2, and 3 in the range B are combined to complete a vast building as a whole.

[0003]

However, in the construction method for constructing a vast building as described above, after constructing the structure in the area A, it is necessary to construct the structure in the area B from one end side. The construction from the first floor to the top floor of each section will be constructed in order, and the next section will be moved. The specifications of each floor are often different and the setup is poor and difficult to construct. There was a drawback that it would be.

[0004] The present invention has been made in view of the above problems, and has as its object to provide a construction method for shortening the construction period of a vast building.

[0005]

The gist of the present invention to solve the above-mentioned problems and achieve the above-mentioned object is to provide a crane loading path at the center of the site when constructing a vast building, After constructing a structure on the site divided into right and left by the entrance path, introducing a crane to the entrance path of the central portion, while moving the crane from one end side to the other end side of the central portion In the construction method of a vast building in which each construction section is constructed and the structure of the left and right premises and the structure of the central part are combined, after constructing the structure on the left and right premises, a traveling rail is provided above the left and right structures. And a portal crane spanning the central portion is slidably provided on the traveling crane, and the central portion is constructed for each floor to construct a vast building, and thereafter, the portal crane is constructed. In the construction method to remove

[0006]

According to the construction method of a vast building according to the present invention, when a structure is constructed at a central portion of a site by a portal crane,
Since each floor can be made into one construction section, construction becomes easy and the construction period can be shortened.

[0007]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a construction method according to the present invention, and FIG. 2 is a front view of the same. In the drawing, reference numeral 1 denotes a crane loading path, 1a denotes a central portion of a site, 2, 3 denotes structures on right and left sites, 4 denotes a traveling rail, 5 denotes a portal crane, and 6 denotes a slab opening. Parts corresponding to those of the conventional example are denoted by the same reference numerals.

According to the construction method of the present invention, when constructing a vast building, the loading path 1 of the lifting crane is connected to the central portion 1 of the site.
a, and constructs structures 2 and 3 on the site divided into right and left by the carry-in path 1. Then, a crane is introduced into a central portion 1a sandwiched between the left and right structures 2 and 3, and In the construction method of a vast building, each section is constructed while the crane 10 is moved from one end side to the other end side of the portion, and the left and right structures 2, 3 and the central portion structure 11 are connected. after constructing the right and left of the structure 2, while laying the running rail 4 at the top of the left and right of the structure 2, wherein the traveling rate of the gantry crane 5 across the central portion 1a
Slidably on the floor 4 and carry in the material while sliding the central crane 5 on the central portion 1a for each floor.
And open slabs for carrying in building materials for later work.
An opening 6 is provided to construct a vast building, and then the portal crane 5 is removed.

The running rail 4 is, as shown in FIG.
It is laid along the loading path 1 above the structures 2 and 3. As shown in FIG. 2, a portal crane 5 having a crane 5a is slidably mounted on the carry-in path 1 on the traveling rails 4 and 4.

Accordingly, a crane is introduced into the left and right premises divided by the carry-in path 1 for carrying the crane 10 as usual, and a crane is introduced into the carry-in path 1 to carry in and assemble building materials. After the structures 2 and 3 are constructed, the portal crane 5 is operated to carry in the materials, construct the pillars 7 on the first floor, etc., and open the slab for carrying in the construction materials for later work. 6 to construct one floor.

Further, the next floor is constructed by the portal crane 5 further upward.

As described above, since the portal crane 5 can be freely slid in the horizontal direction, the floor space on one floor can be made one section, so that the steel frame can be built smoothly and efficiently. It is easy to carry in.

Then, a structure is constructed on the loading path 1 in the central portion 1a of the site, and the structure is joined to the structures 2 and 3 to construct a vast building as a whole. The crane 5 and the traveling rails 4 and 4 are dismantled and removed by another crane.

[0014]

As described above, according to the construction method of a large building of the present invention, the entrance of the crane is provided in the center of the site, and the structure is constructed on the site divided into right and left by the entrance. After that, a crane is introduced into the carry-in path of the central part, and in the construction method of a vast building that combines the structure of the left and right premises and the structure of the central part, after constructing the structure on the left and right premises, Oite at the top of the left and right of the structure
A traveling rail is laid along the carry-in path, and a portal crane that straddles the central portion slides on the traveling rail.
And the central part is connected to the gate type clay for each floor.
The material while sliding the
In order to construct a vast building by constructing a slab opening for carrying building materials in order to construct a vast building and then removing the portal crane, each floor can be converted into one construction section Work efficiency can be improved by smoothly carrying in and building materials, and there is no need to move to the top floor in each section while moving the crane as before, greatly shortening the construction period.
